Your trips

Plan on the couch, use it in the car. Everything stays on this device and works with zero bars.

Print and export are free — it's your trip. Map links open Google Maps; the day route strings every stop into one drive.
Trail Pack caches every stop's conditions and hiker reports on this phone before you lose signal — scattered forum wisdom, turned into something that works deep in the thicket. While you have bars, it quietly re-checks. (For offline map tiles, use Maps → Download offline area once — Google doesn't let apps cache those.)
